TIME-SIGNAL FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 234,634, dated November16, 1880.

Application filed August 11, 1880.

1'0 all whom it may concern:

Be it known that I, HORACE A. W'AYNE, of Manlius Station, in the countyof Onondaga and State of New York, have invented a new and usefulImprovement in Time-Signals for Railways, of which the following is aspecification.

The object of my invention is to furnish an apparatus fitted foroperation bypassing trains to indicate the time of passage forinformation of the driver of a following train.

The invention consists in the combination of a clock with hands and dialas usual, and a clock-movement without an escapement, that moves thehands of the indicating-dial, and having a stop-lever that is releasedby the passing train, the two clocks being so connected that theindicator remains immovable until a train passes, when it is releasedand moves until its hands catch up with or indicate the clock-time, andit is again stopped.

The construction and operation will be described in detail withreference to the accompanyin g drawings, wherein- Figure l is a frontelevation of the indicatin g apparatus, partially in section, andshowing the connections to the track. Fig. 2 is a rear elevation of thebox and clock mechanism. Fig. 3 is a detail view, showing the stop-pawl,and Fig. at is a horizontal section of the box.

Similar letters of reference indicate corresponding parts.

A is the box or housing containing the mechanism for operating theindicators, which box is elevated on a post at the side of the track.(Shown at a.) The front of the box is fitted with a door, I), fittedwith a glass dial, a, and in the box, behind door I), is fitted a plateof ground glass, which at night is to be illuminated by a lamp placed inbox A. There is also a door at the back of box A, which gives access tothe mechanism.

Within the box is a clock-movement, B, of which 0 is the dial. There isalso a second clock-movement, 0, having its center arbor, d, extendedthrough a center opening in the ground-glass plate, so that the handsare visible through door I). The clock-movement O has no escapement, andconsists simply of the necessary gearingfor moving the hands driven (Nomodel.)

by a spring, so that when in operation the hands are rapidly turned.

The winding-arbors of the two movements B G are fitted each with a drumor barrel, as shown at f and g, which are fast upon the arbors, andcorrespond in diameter. To the drums f g are connected the ends of acord or chain, h, which is wound on the drum f of clock B in suchdirection that it unwinds with the spring, and on drum 9 of clock 0, sothat it is wound up as the spring unwinds. On the cord h is hung looselya weight, t, that serves to keep the cord taut.

The escapement-arbor of the movement 0 is provided-with a ratchet-wheel,it, that is en- ,65 gaged by a stop-pawl, I, that is fitted between thefront and back plates of the movement. From the pawl 1 an arm, onextends back above the cord h in such position that when the cord isdrawn taut it raises arm m and moves pawl'l into contact withratchet-wheel k. From the arm m a rod, it, extends downward through thepost to the ground, where it is connected with a lever, 0.

q r are levers contained in a suitable box or trough and extending tonear the track a. At the outside of. the track a curved spring-plate pis connected by one end to the tics, while the other end is held looselyin a suitable guide, as shown most clear-lyin Fig. 5, so that the springcurves upward into a position for being struck and depressed by thepilot of a passing engine.

Beneath plate 19 are springs 8, tending to raise the plate upward. Thisplate 1) is con- 85 nected to the end of lever q, while the outer end oflever r extends above the end of lever o, and is fitted with a slidinglatch, so that as plate 1; moves down the end of lever 1' passes beneathlever 0, and on its return movement raises lever 0, draws down rod 42,and raises pawl Z. The rod 02 is slotted where it connects with pawl I,so that downward movement of the end of lever 0 next to lever r ispermitted without effect on the pawl. 9 5

The operation is as follows: The hands of the dial 6 are first set tocorrespond with the hands of clock B. The cord h is taut and pawl lengaged with wheel is. The movement 0 is thus held at rest while theclock runs. 100

The cord h is gradually unwound from the barrel as the clock continuesto go, and as the movement 0 is at rest the hands of dial 0 continue atthe hour as set. As a train passes the indicator it depresses the plate1), raises pawl l, as before described, thereby permitting the movement0 to turn the hands of dial 0, which will continue until the cord istaut again and has raised arm on and stopped the movement 0. As the cordis wound up to the same extent it was previously unwound, the hands ofdial 0 correspond again with the clock, so that when another trainpasses sooner or later the dial shows the time of the passage of theprevious train, and is again brought into operation to indicate the timethe second train passes. By these operations the time of passage of thelast train is always shown on the dial, and the apparatus needs noattention except to wind it up from time to time.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In railway-indicators, the combination, with clock-work G, fitted tomove the indicating-hands, and time-movement B, of the barrelsf g, cordor chain h, pawl l, having arm m, and connections from the pawl tolevers fitted for movement by a passing train, substantially asdescribed, for operation as set forth.

2. In railway-indicators, the slotted rod n, stop-pawl l, and lever 0,fitted for movement by a passing train, in combination with indicator U,time-movement B, barrels f g, and cord or chain h, the latter fitted toraise pawl and stop the time-movement, as shown and described.

3. The spring-plate p, lovers 1 1", connected together, sliding latch r,fitted in lever 1', lever 0, and slotted rod a, in combination with thestop-pawl l of the indicating mechanism, as and for the purposespecified.
